A lesson here, perhaps, is that measurement comes first. It's trivial to speculate, "hey, here is this unexplored aspect of biology, perhaps it explains x". But the instead we get 50 narrative reviews of such tantalizing ideas before even the most fundamental aspect of science is sorted. Measurement

Yesterday my son pretended he was installing an update on his toy cash register. He just sat there and waited for a bit. Today, my daughter pretended she worked in a store that only sold high protein foods. I think they’re good to go 👌🏽

Preparing a seminar session on happiness economics and I'm once again reminded how liberating it is to be in charge of what I tell students. I can just decide what I think is important for them to know (methods >> individual studies) and then pick examples that are interesting.

The Causal Bandits episode with me is finally up! We talked about a hodge-podge of causal inference and methods issues. I already got one positive testimonial from my boss who listened to the first half and liked it!
